Abstract


The rapid development of IP networks for multimedia communication services and voice over IP telephony technology paved the way forward. SIP as a multimedia communications and voice over IP telephony is an important agreement , much attention in recent years . On the other hand , mobile devices such as laptops rapid increase in wireless Ad Hoc network applications are increasingly widespread. However, the existing standard SIP protocol and not well supported by the wireless Ad Hoc network environment. One of the main difficulties is no infrastructure for wireless Ad Hoc networks can not provide a fixed SIP central server . To solve this problem , we designed and implemented in Ad Hoc environment to provide the basis for the SIP service program . In this paper, SIP technology for clues, analyze voice communications signaling techniques that are commonly used , highlighting the advantages of the SIP protocol . Followed by in-depth analysis of the standard SIP protocol features , hierarchies , message formats and call transaction. This paper gives then no center 's SIP prototype details. The design is based on the original standard SIP to be innovative , critical design including the election of DS (Designated Server) and BDS (Backup Designated Server) mechanism , and exception handling mechanism. This article also gives the realization of the key technologies used in design . Finally , after the realization of the design of experiments carried out testing and evaluation . Experimental results show that the design is feasible , available later in Ad Hoc Networks SIP studies for reference.
